$\mathrm{D}$ and $\mathrm{D_s}$ decay constants in $N_{\rm f}=2+1$ QCD with Wilson fermions

/RQCD Collaboration ; ALPHA Collaboration
We present results for the leptonic decay constants of the D and D$_{\rm s}$ mesons from $N_{\rm f}=2+1$ lattice QCD. We employ a set of 49 high statistics gauge ensembles generated by the Coordinated Lattice Simulations (CLS) effort utilising non-perturbatively improved Wilson fermions and the tree-level Symanzik improved gauge action at six values of the lattice spacing in the range $a = 0.098\,$fm down to $a = 0.039\,$fm, with pion masses varying from around $420\,$MeV down to below the physical point.

Terbium-152 is one of four terbium radioisotopes that together form a potential theranostic toolbox for the personalised treatment of tumours. As 152 Tb decay by positron emission it can be utilised for diagnostics by positron emission tomography. [...]

We present an update of the scale setting for $N_f=2+1$ flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with $2+1$ flavors of non-perturbatively improved Wilson fermions generated by CLS for improved precision. [...]

FLAG Review 2021
/ Flavour Lattice Averaging Group (FLAG) Collaboration
We review lattice results related to pion, kaon, $D$-meson, $B$-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factor $f_+(0)$ arising in the semileptonic $K \to \pi$ transition at zero momentum transfer, as well as the decay constant ratio $f_K/f_\pi$ and its consequences for the CKM matrix elements $V_{us}$ and $V_{ud}$.

Chemical Purification of Terbium-155 from Pseudo-Isobaric Impurities in a Mass Separated Source Produced at CERN
/ Webster, Ben (Teddington, Natl. Phys. Lab ; Surrey U.) ; Ivanov, Peter (Teddington, Natl. Phys. Lab) ; Russell, Ben (Teddington, Natl. Phys. Lab) ; Collins, Sean (Teddington, Natl. Phys. Lab) ; Stora, Thierry (CERN) ; Ramos, Joao Pedro (CERN ; Leuven U.) ; Köster, Ulli (Laue-Langevin Inst.) ; Robinson, Andrew Paul (Teddington, Natl. Phys. Lab ; Manchester U.) ; Read, David (Teddington, Natl. Phys. Lab ; Surrey U.)
Four terbium radioisotopes ($^{149, 152, 155, 161}$Tb) constitute a potential theranostic quartet for cancer treatment but require any derived radiopharmaceutical to be essentially free of impurities. Terbium-155 prepared by proton irradiation and on-line mass separation at the CERN-ISOLDE and CERN-MEDICIS facilities contains radioactive$^{139}$Ce$^{16}$O and also zinc or gold, depending on the catcher foil used.
